Fig. 3 is a top view of thelower shovel blade retaining plate of mydevice. I V Fig. l is a top view of my replaceable shovel blade only. VFig. 5 is an enlarged sectional view transversely of the blade device,as on line 55 in Fig. 3.

Fig. 6 is a perspective fragmentary View, showing the left endof thelower blade retaining plate shown in Fig. '3.

Referring to the drawing byreference numerals, 10 designates a metalshovel body or ladle of approximately desired form and to the rear partof which is removably fixed as by means of a U-bolt 11 and a clip 12 orequivalent means, a handle 13. The front edge part of the ladle is ofcourse a transverse plane relative to the handle 13 and the constructionthereof embodies a replaceable blade as will presently be described. his

' well known that this front edge of any shovel is the first part of theladle to be worn out or is worn uneven, curls up or isotherwise-deformed by wear and tear.

' 10A is the base of the shovel ladle, usually flat and having atransverse forward edge 1013. The upper edge or rim of the ladleproper-is preferably formed beaded as 10C and inclosing a heavy wire it(see Figs- 1 and 2), said wire being preferably tapered toward its two,forward ends which project beyond the said edge 10B fora purpose whichwill now be set forth.

The front edge part of my improved shovel comprises an approximatelyquadrangular elongated blade 15'-removably retained between a pair ofplates 16 and 17 of which 16 is an upperplate and 17 a lower adapted tobeengaged against the sloping vided' with extensions or ears 17E at itsplate. The blade1 5 projects forward from the aligned front edges ofplates 1617, asshown, when in operative position. Plate 16 is offsetlongitudinally and downward, making its rear part a lowered ledge 011which the front edge part 1013 of the ladle 7 bottom 10A is placedagainst the offset part and thus 10A and the upper part of plate16 areon a common plane both ways from the offset 16A (see Fig. 5). The lowerplate 17 is fixed to the rear and lower offset part of plate 16 by meansof a series of rivets 18, some or all of which rivets may be passedthrough ladle bottom 10A to secure said three parts together firmly.Obviously the plates 1617 are in parallel spaced and fixed relationto'each otherforward of the offset, forming areceiving pocket'in whichthe blade 15 is retained. The means for retaining the blade comprisestwo'or more fixed studs 19 projecting upwardly from the lower plate 16.Said plate is also provided at each end with upwardly projecting fixedblocks, 20R- and 20L, each with corresponding angular face 20R and 20L,said blocks being of a thickness corresponding to thickness of blade 15.

. Said blade is provided at its left end with i a notch .15N having asloping side 15N so face 20L of block 20L and at the right hand fendblade 15is cut off angularly as at 15A to provide a face to bear againstthe angular face of block 20R (see dotted position of blade 15 in 3)when the blade is in f operative position. "The inneredge part of theblade is further provided with two or more angular slits 21, one foreach stud'19, so thatthe blade can be inserted between the plates withthe slits 21 guiding it inwardly and angnlarly to the innermostposition, shown dotted in Fig. 3. Then thetop plate 16 is pressed downon top of the blade, said plate being provided with apertures to engageover the parts of studs 1'9 projecting above the blade and said latterparts hammered down to hold the blade and plates together firmly. Thelower plate 17 is proopposite ends and it will be readily understoodthat these ears are bent inwardly, after placement of blade 15, andthence beaded around the protruding front ends of the wire 14-, as fromdotted to full line positions of said ears distinctly shown in Fig. 1(see also Fig. 3)

The studs 19 need not necessarily be rivcted but to further hold theblade 15 in place I provide vertically registering apertures 21 in theplates 1617 and a like aperture 22 in the blade 15, all three to bealigned when the blade is in position and through which a holding rivet23 is placed and clinched (see Figs. 1 and 5).

In this latter form it will be readily understood that a worn blade 15is easily replaced by simply chipping off the end of rivet 23, removingit and taking out the old blade, then replacing it with a new one asdescribed. The advantages of this construction are so obvious as to needno further description thereof. A feature of this invention desired tobe stressed is the wire reenforcing bead 14 tapered toward both ends. Ihave illustrated and described my invention in a preferred embodimentthereof, variations of details and application being possi le withoutdeparting from the scope and spirit of the invention.

I claim:

l. A shovel ladle comprising a metal blade with plane transverse frontedge, the body of said ladle formed with rearwardly rising edgeportions, said edge portions comprising a continuous head, a single wirewithin aid bead and tapered toward its ends, and

a front blade device removably fixed to said transverse front edge ofthe ladle and comprising a double plate, the upper part of said plateoffset to provide a forwardly directed opening between the two parts ofsaid plate, a front shovel blade adapted to be slidably inserted in saidopening and guide plates fixed to said lower plate to guide and retainsaid blade in said opening and further means fixed in said lower plateto guide the blade to operative position and said blade normallyprojecting forward of the front edge of said plate member.

2. The structure specified in claim 1 in which said offset part of theplate is downwardly at the rear edge part thereof and said offset rearpart adapted to bear against the lower front edge part of the shovelproper and means for securing said parts together.

3. A shovel ladle comprising a metal blade with plane transverse frontedge, the body of said ladle formed with rearwardly rising edgeportions, said edge portions comprising a continuous bead, a single wirewithin said head and tapered toward its ends, and a front blade deviceremovably fixed to said transverse front edge of the ladle and comprisina double plate, the upper part of said plate offset to provide aforwardly directed opening between the two parts of said plate, a frontshovel blade adapted to be slidably inserted in said opening and guideplates fixed to said lower plate to guide and retain said blade in saidopening and further means fixed in said lower plate to guide the bladeto operative position and said blade normally projecting forward of thefront edge of said plate member, said latter guide means comprisingfixed studs in the lower plate and said plate provided with angularlyand rearwardly directed slits one for each said stud, the blade adaptedto he slid rearwardly between the said plates with its slit partssimultaneously guided by and straddling said studs, said plates and saidblade provided with apertures adapted to register verti *ally int tionof a rivet to hold the plates and blade in correct relative positions. Ashovel ladle comprising a metal blade with plane transrcerse front edge,the body of said ladle formed with rearwardly rising edge portions, saidedge portions comprising a continuous reinforcing head toward its ends,said wire ends protruding forwardly from said beaded parts, a. removableshovel blade arranged transversely of the ladle and forward of its frontedge, means for removably retaining said blade in about a common planewith the bottom of the ladle, said latter means comprising a pair ofplates with heir front portions apart and adapted to retain said bladetherebetween, endwise integral extensions provided on the lower of saidtwo plates and said protruding parts of the beading wire normallyextending over said extended parts, and said latter parts adapted to bebent inwardly over and about said wire ends for the purpose set forth.

In testimony whereof I afiix my signature.
